BACKGROUND:Currently, one of common methods is discectomy, nerve root decompression and fusion rigid fixation from the midline approach for disc herniation which is inefficient by conservative treatments. Thus, it is causing degeneration and limiting lumbar physiological activity of adjacent segments. The treatment of non-fusion lumbar disc herniation with the traditional posterior midline incision approach has some disadvantages such as big incision, wide peeling, and back muscle denervation.
OBJECTIVE:To observe therapeutic effects of dynamic stabilization system through Wiltse approach on lumbar disc herniation, and to compare the outcomes with traditional posterior approach.
METHODA total of 46 patients, who had undergone discectomy and internal fixation using dynamic stabilization systems for lumbar disc herniation at the Renmin Hospital of Wuhan University from January 2011 to January 2013, were enrol ed in this study. The operation was performed through the traditional posterior approach in 25 patients and Wiltse approach in 21 patients.
RESULTS AND CONCLUSION:Al 46 patients were fol owed up for 7 to 31 months (averagely, 13.8±2.4 months). The length of incision, intraoperative blood loss, and postoperative drainage amount were less in the Wiltse approach group than in the traditional posterior approach group (P<0.05). No significant difference in visual analog scale scores and operative time was detected between the two groups at 1 week and 6 months after fixation (P>0.05). Radiographs revealed that the position of implants was good in al patients, no loosing or breakage. These data verified that the early effect of dynamic stabilization system through Wiltse approach for lumbar disc herniation is similar to that of traditional posterior approach.

Objective To investigate the feasibility and application scope of the looping technique by using a gooseneck snare and a loach guide wire in retrieving tubular foreign bodies within the vascular or ureteral duct. Methods During the period from July 2009 to Dec. 2013, six patients with ruptured catheter were admitted to authors’ hospital. All six patients were females. Three patients had internal ruptured peripherally inserted central venous catheter (PICC), one patient had ruptured implantable venous access port catheter and two patients had replacement of double “J” ureteral catheter stent. By using looping technique, i.e. a loach guide wire and a gooseneck snare were separately placed at the two ends of the tubular foreign body, then the gooseneck snare entangled the soft leading end of the loach guide wire to form a annular structure to seize the ruptured tubular catheter and then to pull it out of the body. Results With the help of the looping technique, the internal ruptured catheter or the double “J” ureteral catheter was successfully removed in all the six patients. Conclusion For the retrieval of the tubular foreign bodies within the vascular or ureteral duct, the looping technique by using a gooseneck snare and a loach guide wire is an effective and fast treatment. Therefore, this technique should be recommended in the clinical practice.

Objective To compare the clinical effects of intramedullary nails and locking compression plate in the treatment of femur shaft fracture.Methods The clinical data and follow-up records of 43 patients with femur shaft fracture treated by intramedullary nails and locking compression plate were retrospectively reviewed.Including 31 males and 12 females with an average age of 40.07 years(25 to73).According to AO classification:5 cases were type A,24 cases were type B,14 cases were type C.26 patients in group A treated by intramedullary nails and 17 patients in group B treated by locking compression plate.Operation time,fracture union time,blood loss and complications were compared between the two groups.The Karlstrom and Olerud result were compared and analyzed.Results All patients were followed up at an average of 15 months(range 5-24) after surgery.According to Karlstrom and Olerud score system,the excellent and good rate of group A was 88.4％,higher than the group B 82.3％.But there was no significant difference between the two groups.In group A:the operation time (113.77 ±20.14)min,the blood loss in the operation (386.74 ± 65.16) ml,clinical bone healing (15.52 ± 1.77) weeks.All these outcomes were better than group B (P ＜ 0.01).One case in group A appeared screw loose,but X-ray showed the nail stable,the bone wasn't displacement.One case in group B appeared broken plate 1 month after operation,and received twice operation,the clinical outcome was good as well.Another 1 case with fracture delayed union in group B,after internal fixation removed,we check the X-ray showed bone union.Conclusion Two methods of treatment femur shaft fracture can all reach the above requirement.Fixation of intramedullary interlocking nail is the preferred surgery than locking compression plate.

Objective To compare the effect of allograft and autograft of bone-patellar tendon- bone (B-PT-B) under arthroscopy in reconstruction of anterior cruciate ligament (ACL).Methods The injured ACL was reconstructed under arthroscopy by using autograft of B-PT-B in 30 cases and al- lograft of B-PT-B in 28 cases from January 2000 to August 2003.After over twelve months follow up,a comparison was done on rehabilitation of quadriceps femoris,knee stability,the Lysholm's score of knee and the enlargement of tunnel in both groups.Results Both groups obtained marked improvement of knee stability and symptoms after operation.But in the early time,the rehabilitation of quadriceps femoris in the ailograft group is faster than that in the autograft group.The rehabilitation of quadriceps femoris, knee stability and the Lysholm's score of knee were similar at 12th month (P＞0.05).There could be seen enlargement of tunnel in both groups,with more in the allograft group (P＞0.05).Conclusion For arthroscopic reconstruction of anterior crucial ligament (ACL),allograft of B-PT-B is good substitute, for it is characterized by effectiveness,convenience and minor side effect.

This paper presents a non-invasive and non-ionizing radiation method for assessment of osteoporosis by analyzing in vivo MR images. Texture features (entropy, coarse, etc...) derived from co-occurrence matrix and neighborhood graystone difference matrix are obtained. These features are significantly different between patients and control subjects. Then the grayscale MR image is transformed to the binary image, The shape and topology features (area, skeleton length, euler number, etc. ) obtained from the binary image show too significant differences between patients and control subjects.

Objective To study the feasibility of using gooseneck snare combined with 0.035 inch loach guidewire for subintimal angioplasty in iliac artery occlusion , and to discuss its clinical indications. Methods During the period from October 2011 to May 2013, 3 cases with unilateral complete iliac artery occlusion were admitted to authors’ hospital. As the guidewire inserted from the healthy side could not returned into the true lumen once it entered into the subintimal space of the iliac artery , the puncture at the diseased side was carried out and the guidewire was pushed into the artery , but the catheter and the guidewire could not converge or anastomose in the subintimal site , gooseneck snare had to be used to grab the guidewire in subintimal site as to establish a path and completed the angioplasty. Results Successful and safe balloon dilatation and stent implantation were accomplished in all the 3 patients , and the patients complained of no special discomfort. Conclusion In performing the subintimal angioplasty for patients with iliac artery occlusion, the use of gooseneck snare combined with retrograde insertion of guidewire should be considered when it occurs that the guidewire can not return into the true lumen after it enters into the subintimal space. Nevertheless, gentle manipulation is first important in order to avoid the possible rupture of vessels.

Objective To assess the safety and efifcacy of a novel biodegradable polymer-coated Cobalt-Chromium alloy sirolimus-eluting stent in a porcine model. Methods Bare metal stents (BMS) (n=15), commercial available EXcellstents (n=21), and Cobalt-Chromium alloy PLAG-coated sirolimus-eluting stents (Co-P-SES) (n=21) were implanted in left anterior descending coronary (LAD, n=28)and left circumflex coronary (LCX, n=13), and right coronary artery (RCA, n=16) of 30 mini-pigs randomly. Coronary angiography was performed 28 days, 90 days and 180 days after the stenting procedure to evaluate luminal loss (LL), and then, histomorphology analysis was performed. Results 28 days and 91 days after the implantation, there were no significant differences in LL, neointimal area, Inflammation score and endothelialization score among the three groups. 28 days after the implantation, better endothelialization was observed in Co-P-SES group compared with EXcellgroup under scanning electron microscope. 182 days after the implantation, there were larger lumen area and less neointimal area in Co-P-SES group compared with EXcellgroup under similar internal elastic lamina area[(4.31±0.94) mm2 vs. (2.62±1.17) mm2, P=0.020];[(1.87±0.53) mm2 vs. (0.84±0.41) mm2, P=0.004]with statistical significance. Conclusions The novel biodegradable polymer-coated Cobalt-Chromium alloy sirolimus-eluting stents showed similar safety compared with commercial available EXcellstents. There would be a better potential of the novel stent on inhibiting the neointimal proliferation and endothelialization. However, further preclinical study including long term endpoints and clinical study should be conducted in order to evaluate the safety and effectiveness of the novel Co-P-SES.

In order to summarize and perfect the basic skill practicing method in acupuncture teaching and form a characteristic teaching, the research on skill training and technique improving of acupuncture and tuina major was carried out. The undergraduate students in acupuncture and tuina major from College of Acupuncture-Moxibustion and Tuina were randomly divided into an experimental group and a control group. Students from both groups received the basic courses of acupuncture-moxibustion and tuina as requested in the syllabus and the special teaching was added to the experimental group, namely "three practice" (strength practice, coordination practice, targeted practice of acupuncture basic skills) and "three enlightenment" (technique enlightenment, mind and qi enlightenment, efficacy enlightenment). During and after the courses, the teaching effectiveness was evaluated on the basis of needling manipulation. The peacetime score in the experimental group was superior to that in the control group (38.03 +/- 1.14 vs 33.25 +/- 1.31, P < 0.05), the total score in the experimental group was superior to that in the control group (84.03 +/- 6.30 vs 78.05 +/- 6.55, P < 0.05). The special teaching method of "three practice" and "three enlightenment" can improve the effect of skill training teaching method. It highlights the unique feature of central plains by integrating the essence of Shaolin internal qigong and Chen-style Taiji, it can also provide new ideas for the practical teaching of TCM professional courses and the construction of characteristic professionals.
